The name of the populous village near Porto Venere dates back to the followers of Madonna delle Grazie, established by the Benedictine monks of Monte Oliveto who settled in the secluded bay of the Gulf of La Spezia, building both the convent and the church, dedicated to Nostra Signora delle Grazie, or Our Lady of Grace.
The pride of the village are its shipwrights and caulkers, renowned and highly sought after since the early thirteenth century.
The village is best known for underwater activities. The divers of Le Grazie have been called to employ their great skill and courage in waters around the world. So proud is the town that the municipal council of Porto Venere voted to call the village "The City of Divers".
